Skate wheel structure

ABSTRACT

A skate wheel structure includes a main wheel section and at least two auxiliary wheel sections at respective sides of the main wheel section. The auxiliary wheel sections are integral with the main wheel section. The outer diameter of each auxiliary wheel section is smaller than that of the main wheel section to increase contact surface with the ground so as to provide a stable rolling.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a skate wheel structure, more particularly, toa main wheel section integral with a pair of auxiliary wheel sections atrespective sides of the main wheel section to increase contact surfacewith the ground so as to provide the stability of rolling.

2. Description of the Related Prior Art

A conventional in-line skate on the market is hard to keep balance inparticular to new riders or to younger kids. An accident happens often.Sometimes kids may even get hurt.

SUMMARY OF THE INVENTION

It is the primary object of the present invention to provide a skatewheel structure, which has a main wheel section integral with a pair ofauxiliary wheel sections at respective sides of the main wheel sectionto increase the stability of rolling.

It is another object of the present invention to provide a skate wheelstructure, which is easy to learn skate skill.

It is a further object of the present invention to provide a skate wheelstructure, which is easy to maintain and saves manpower.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of a first embodiment of the presentinvention;

FIG. 2 is a side view of the first embodiment of the present invention;

FIG. 3 is a rear view of the first embodiment of the present invention;and

FIG. 4 is a rear view of a second embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 1 and 2, a first embodiment of the present inventionis a rear wheel and comprises a main wheel section 1 and at least twoauxiliary wheel sections 11, which is pivotally connected to a skatebody 2 and incorporated with a front wheel 3 and a brake 4. Theauxiliary wheel sections 11 are provided at respective sides of the mainwheel section 1 and integral with the main wheel section 1. The outerdiameter of each auxiliary wheel section 11 is smaller than that of themain wheel section 1.

As shown in FIG. 3, the skate of the present invention is in operation,when making a turn, one of the auxiliary wheel sections 11 and the mainwheel section 1 will be encountered with the ground. This increasescontact surface of the wheel with the ground, providing a betterstability to the rider.

As shown in FIG. 4, a second embodiment of the present invention isstill a rear wheel and comprises a main wheel 1A and two auxiliarywheels 11A, which are formed separately and then coupled together.

1. A skate wheel structure comprising a main wheel section and at leasttwo auxiliary wheel sections at respective sides of said main wheelsection.
 2. The skate wheel structure, as recited in claim 1, whereinsaid auxiliary wheel sections are integral with said main wheel section.3. The skate wheel structure, as recited in claim 1, wherein each saidauxiliary wheel section has an outer diameter smaller than that of saidmain wheel section.
